Electricity is a vital part of our everyday lives, supplying everything from the lights of our homes to the devices we use every day.  However, electric systems may be complex, knowing how they work isn’t easy. In this article we’ll breakdown the components that make up an electric system, and explain how circuits work to power devices and appliances. Our residential electricians can handle any electrical jobs you need.

The components of an electrical system

A home’s electrical system includes a number of essential components that work to provide power throughout homes. They include:

Breaker box: the central distribution point for electric power in a home in which the power is split into various circuits

Switches and outlets: the points at which electricity is supplied to appliances and devices

Wiring: the electrical wires that transmit electricity from the breaker box, to the outlets and switches

Electrical appliances and devices: the appliances and devices that require electricity to function.

Electrical Circuits

A circuit of electricity is one that lets electricity flow from the main source (the breaker box) to the appliances and devices in a home. There are two types of electrical circuits that can be found in a home that are 120-volt and 240-volt circuits. 120-volt circuits are utilized for the majority of household appliances and appliances, whereas 240-volt circuits are used to power larger appliances, such as air conditioners and electric dryers.

Electrical circuits work by creating the loop which allows electricity to flow from the source to the appliance or device. The loop is comprised of a hot cable that is the conduit for electricity, a neutral wire that completes the circuit as well as a ground wire that provides the pathway for electricity to travel to the ground in case there is a problem.

Understanding Electrical Wiring

Electrical wiring is available in many kinds, such as non-metallic sheathed cable (NM) and armored cable (AC), and conduit. Each kind has its advantages and disadvantages and the selection of the wiring type is contingent upon the particular requirements for the particular installation.

The electricity travels through wires by creating a flow of electrons that travel through the wire. The electrons flow through the wire from source, to appliance or device and then back to the source through the neutral wire. It’s essential to ensure that the wiring is put in place and maintained properly, since defective wiring could lead to electrical hazards like shocks and fires.

Common Electrical Issues

Common electrical issues in homes include tripping light bulbs, flickering breakers and disconnected outlets. These problems can be caused by a variety of factors such as overloading circuits poor connections, or faulty wiring.

If you are experiencing one of these problems, it is essential to determine the root cause and take steps to correct the issue. In some cases it may be necessary to contact an accredited electrician to inspect and repair the wiring.
